Summary
Hercules requires a permit before any building, structure, electrical, gas, mechanical or plumbing work begins, per Section 9-1.03 of the Municipal Code.

The City of Hercules may prosecute violations of this Title as misdemeanors in addition to any other remedies provided in this Code or allowed by law. Section 1-4.01 outlines the penalties for any failure to comply with any of the requirements of the Municipal Code for either misdemeanors or infractions. Work commencing before permit issuance. Any person who commences any work on a building, structure, electrical, gas, mechanical or plumbing system before obtaining the necessary permits shall be subject to double fee penalty for all required permits as allowed by the California Building Codes.

Full Breakdown
Title 9 of the Hercules Municipal Code adopts the 2025 California Building Code, Residential Code and related technical codes through Section 9-3.01, which incorporates Contra Costa County Ordinance No. 2025-19 (approved by the Board of Supervisors on November 4, 2025) under the authority of California Government Code Sections 50020 through 50022.9. Because Hercules contracts with Contra Costa County for building inspection services, Section 9-1.02 directs that every reference in this Title to the 'building official,' 'building inspector' or 'City building official' means the county director of building inspection or a duly authorized deputy acting as the City's representative, alongside the City Manager, Community Development Director or City Engineer when they enforce the Title.
Section 9-1.03 sets the penalty structure for skipping the permit step: any violation of a designated code section is an infraction unless the Title says otherwise, though the City may also prosecute a violation as a misdemeanor, with the general penalty schedule set out in Section 1-4.01. A person who commences building, electrical, gas, mechanical or plumbing work before obtaining the necessary permit is charged double the normal fee for every permit that work required. If work continues after the building official has posted a stop-work order, the City issues an administrative citation under the procedure in Section 1-4.02, unless the work is directed by the building official to correct the violation or unsafe condition itself.
A denied or disputed permit decision can be appealed to the three-member Board of Appeals (Section 9-2.01), whose members serve two-year terms under Section 9-2.03. An appeal must be filed in writing with the Board's office within ten days of the protested decision, along with the filing fee set by City Council resolution (Section 9-2.09); the Board's ruling can then be appealed to the City Council within ten days under Section 9-2.11.
Violations & Fines
Working without a permit is charged as double the standard permit fee for every permit the job required, on top of any correction costs (Section 9-1.03). Ignoring a posted stop-work order escalates to an administrative citation under the Section 1-4.02 procedure. The City treats a Title 9 violation as an infraction by default but may instead prosecute it as a misdemeanor, with fines and other remedies set under the general penalty schedule in Section 1-4.01.
